    Abstract

    It is always difficult to test the bearing capacity of soil under constructed buildings. Thus, the adoption of the Rayleigh wave method to address this problem is investigated in this study. The fundamental of the Rayleigh wave velocity method in geological engineering is initially presented. The in situ shear wave velocity can be obtained by Rayleigh wave method. Rayleigh wave velocity and soils static load tests are conducted on several different kinds of soil. Thus, the fitting formula between shear wave velocity and soil bearing capacity under specific soil conditions is determined. A reconstruction engineering project that uses the Rayleigh wave velocity method to test the bearing capacity of soil under a constructed building is then studied. Rayleigh wave velocity tests are conducted based on this fitting formula to analyze the soil bearing capacity. The reconstruction is proven to be successful by settlement observation. The fitting formula between shear wave velocity and soil bearing capacity are probably different for various kinds of soil. Therefore, the application of the wave velocity test method in detecting the soil bearing capacity of a constructed building has to be studied before it can be popularized.
